Title: Control system of gradation of color thermal printer
Inventor: SHINYA TADAO
IPC: B41J2/36
Filed: 1988-06-20
Abstract: PURPOSE:To obtain constant printing density regardless of the magnitude of load even at any gradation level by determining the quantity of the lengthening of the conduction time at the time of the drop of the supply voltage of a head on the basis of a correction data. CONSTITUTION:Fundamental conduction data are set so that specified printing density is acquired under the state in which a voltage drop DELTAV1 can be ignored. Simultaneous conduction heating-element number Pi is increased successively so that an output from a voltage drop detector is brought to di=1, 2, 3 at a gradation level i=1 in ink A, and conduction pulse width coefficients kA11, kA12, kA13 are set so that printing density in each case is made to the same fixed density as the voltage drop DELTAV1 can be ignored. Even when load is changed while the gradation level is brought to i=2, conduction pulse width coefficients kA21, kA22, kA23 are set so that printing density is brought to specified density at all times. Likewise, a coefficient data table is acquired even regarding ink B. Printing is conducted while conduction pulse width data are determined on the basis of correction data obtained.

Title: Water tube boiler
Inventor: ABE TADAAKI
IPC: F28D7/16
Filed: 1995-05-26
Abstract: PURPOSE: To enhance the heat transfer efficiency by disposing a plurality of burner water tube groups near a burner, and disposing the groups formed by a plurality of water tube walls. CONSTITUTION: Fuel gas is mixed with the air forced by a blower, burnt by a burner 5 to generate a flame 6. The flame 6 collides with the burner water tube group 8 to be heat exchanged, and the temperature of the flame 6 is lowered. The excess drop of the flame temperature reduces NOx, but CO is reversely easily generated. Even when the CO of high concentration is generated, the combustion gas is branched to the rightward and leftward directions to flow to wide spaces 9A, 9B between the water tubes, the residual CO is oxidized here to complete combustion reaction as CO2 gas, and hence the CO is eliminated. Thereafter, the combustion gas flows at a high speed in rear water tube groups 12A, 12B to transfer heat to the tube groups 12A, 12B, and is exhausted from a flue 11.  Thus, the high heat transfer effect and low NOx ratio are performed by the group 8, and the low CO is performed by the combustion in the spaces 9A, 9B between the tubes.

At the same time, the sheath component polymer B after being diffused and shunted by a 1st annular groove 6 is dispersed and flows in a 2nd annular groove 9 through respective small holes 7 and then the polymer while receiving the drawing resistance of a small gap flows in the molding exit 8 from the entire periphery and exits while covering the core component polymer A. Consequently, the sheet type photoconductor C which has the uniform-thickness sheet core material (a) covered with the uniform- thickness sheath component polymer (b) is obtained.
